What is business opening date selection?
Grand opening date selection (開市擇日 kāi shì zé rì) is the classical Chinese practice of choosing a first day of trade whose almanac pattern favours openings and does not clash the owner's chart. This selection computes ranked opening dates from your BaZi (八字 bā zì) chart for 19 USD.
Key Takeaways
- This page follows the Chinese almanac tradition (通勝 Tōng Shèng), a different system from the Vedic muhurat used for Hindu opening dates.
- Opening favours the Open (開 Kāi), Success (成 Chéng), and Full (滿 Mǎn) officers; the Break (破 Pò) and Close (閉 Bì) officers are traditionally avoided for a first day of trade.
- The owner's chart is the personal layer: a generically favourable day that clashes the owner is excluded.
- Every recommended date prints its day pillar, Day Officer, and Mansion star, checkable against any published almanac.
- Every selection carries a 7-day satisfaction refund.

One owner in twelve meets a zodiac clash on any given recommended date, and the day-pillar checks catch more cases the generic table cannot express.
A day whose branch is Rooster stands opposite the Rabbit branch, so a Rabbit-year owner meets a personal clash on a date the generic list marks excellent for openings.

A generic dates list
A generic business opening date selection list grades one calendar for everyone at once. It never saw your chart.
This selection
This selection computes ranked dates from your own Four Pillars (八字 bā zì), removes any day that clashes you, and prints the day pillar, Day Officer, and Mansion star so you can verify each one in any published 通勝 (Tōng Shèng).
One tradition, stated plainly
Search results for opening dates mix two systems that share nothing but the question. This page follows the classical Chinese method: 開市擇日 (kāi shì zé rì, business opening date selection) in the 通勝 (Tōng Shèng) almanac tradition, systematized by the Qing imperial compendium 協紀辨方書 (Xié Jì Biàn Fāng Shū). The Vedic muhurat system used for Hindu opening ceremonies is a different tradition with different mathematics, and we do not blend the two.
In the Chinese method, the first day of trade is one of the classical timed events, alongside weddings and moving in. The classical sources describe the opening day as the pattern a business keeps returning to: the day the doors first opened, the first exchange made across the counter. Choosing it deliberately is the whole discipline.
How the method grades an opening date
On the almanac layer, opening favours the officers whose motion matches a launch: Open (開 Kāi), Success (成 Chéng), and Full (滿 Mǎn) from the Twelve Day Officers (建除十二神 jiàn chú shí èr shén). The Break officer (破 Pò) and the Close officer (閉 Bì) are avoided for a first day of trade, and the structural exclusions, Month Breaker (月破 yuè pò), Year Breaker (歲破 suì pò), and the Ten Evils Great Defeat days, are struck before any scoring.
The personal layer belongs to the owner. A day that clashes (沖 chōng) the owner's zodiac branch or day pillar is excluded outright, and in Wu Xing terms the ranking favours days that reinforce the element the owner's chart needs (用神 yòng shén). A business opening is a beginning made by a person, and the method insists on checking the person.
Why a generic opening-dates list is not enough
Published lists of grand opening dates grade the calendar for everyone at once, which is exactly what a printed almanac must do. The limitation is structural: one owner in twelve meets a zodiac clash on any given recommended date, and the day-pillar checks catch more cases the generic table cannot express.
The pattern looks like this: a day whose branch is Rooster stands opposite the Rabbit branch, so a Rabbit-year owner meets a personal clash on a date the generic list marks excellent for openings. Our selection removes such days for you before ranking, and prints every fact it used so you can check it against any published 通勝.
Resolve that check against your own chart. Ranked business opening date selection, verifiable in any almanac, 19 USD.

What is grand opening date selection?
Grand opening date selection (開市擇日 kāi shì zé rì) is the classical Chinese practice of choosing a first day of trade by the almanac's day grades and the owner's own chart. Officers such as Open (開 Kāi) and Success (成 Chéng) are favoured, breaking and closing days are avoided, and any day that clashes the owner's chart is excluded.
Is this the same as a muhurat opening date?
No. A muhurat is chosen in the Vedic astrological tradition used for Hindu ceremonies, with its own calendar mathematics. This selection follows the classical Chinese almanac tradition (通勝 Tōng Shèng) as systematized in the Qing compendium 協紀辨方書. Both are legitimate traditions; they are simply different systems, and mixing their rules produces neither.
How are my opening dates computed?
Your opening dates are computed from the owner's BaZi (八字) Four Pillars chart and your chosen window. The engine grades each day on the almanac layer, excludes personal clash days, ranks the survivors, and attaches a favourable opening hour. The computation is deterministic and every printed fact is checkable in a published almanac.
What if I open online with no physical launch day?
The method still applies: the classical category 開市 (kāi shì) covers the first day of trade, which for an online business is the day the store goes live and the first sale can occur. Choose the window around your intended launch, and the selection ranks days the same way it would for a shopfront.
How is the opening date reading delivered, and what does it cost?
The business opening date selection costs 19 USD. After secure Stripe checkout, the selection is computed from your inputs and emailed to you with a 7-day satisfaction refund.
